Frigate stable **0.17** uses **MemryX SDK 2.1**.

To avoid introducing potential issues, we are keeping this release on SDK 2.1. We plan to update the MemryX SDK in the Frigate development branch soon, and that update should be included in a future stable release.

* * *

#### To upgrade or downgrade, first remove the currently installed MemryX SDK packages:

```auto
sudo apt-get remove memx-*
sudo apt purge memx-*
sudo rmmod memx_cascade_plus_pcie

```

* * *

#### Then install [MemryX SDK 2.1](https://developer.memryx.com/2p1/get_started/install_runtime.html) and hold the package versions:

```auto
sudo apt update
sudo apt install memx-drivers=2.1.1-1.1 memx-accl=2.1.2-1 mxa-manager=2.1.1-1
sudo apt-mark hold memx-drivers memx-accl mxa-manager

```

Installing `memx-drivers` will also flash the **2.1 firmware**. After installation, **reboot the system**.

* * *

For more detailed installation instructions, please refer to: [Install Runtime](https://developer.memryx.com/2p1/get_started/install_runtime.html#first-time-installation)

If needed, you can also review the firmware update instructions here in case the firmware is not updated automatically: [Update Firmware](https://developer.memryx.com/2p1/tutorials/how_to/update_firmware.html#update-firmware)

Hi, Frigate has not been upgraded to SDK 2.2 yet. In the next Frigate release, we plan to upgrade it with our upcoming SDK version. Thank you.
